HYD RANT.

SPECIFICATION forming part of Letters Patent No. 470,842, dated March15, 1892.

Application filed November 7. 1890. Serial No. 370.682. (No model.)

To all whom it may concern: v

Be it known that I, JOSEPH REDICAN, gentleman, ot' the city of Toronto,in the county of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Hydrants, of which the followlng1s a specification.

My invention relates to improvements in hydrants, in which the cut-oh.valve at the main is connected to and operated by a rod which passesthrough the center and projects through the top of the hydrant toreceive the crank-handle; and the object of the inventlon is toconstruct a cut-off valve within the hydrant-plug which will shut offthe water automatically without the necessity of turning off the valveat the main; and it consists, essentially, of a valve located at theinner end o f the hydrant-plug and connected to the cylindrical sleevewhich moves within the plug, the Said sleeve, when the coupling of thehose 1s being screwed on, being forced inwardly against the pressure ofthe Water by the ring corresponding in diameter to the sleeve andextending inwardly to the tail-piece of the coupling; but when thecoupling is beingunscrewed the pressure of the water causes the valve toresume its initial position and shut off the water, substantially in themanner hereinafter more particularly explained.

Figure lis a perspective view of the hy drant. Fig. 2 is a perspectivesectional detail exhibiting my invention. Fig. 3 is a detail of thevalve.

In the drawings like letters of reference indicate corresponding parts.

A- represents the hydrant-plug leaded or otherwise suitably secured tothe body of the hydrant.

B is the cut-off valve, which is connected by the bars C to thecylindrical' sleeve D.

I is an extension-ring corresponding in diameter to the sleeve D andextending from the tail-piece j of the hose-coupling J.

In Fig. 3 it will be noticed that the valve and cylindrical sleeve D areconnected together by three bars C, so as to leave large open spaces forthe free passage of the water.

Although I show this method of connection,

it will be understood, of course, that any other 5o simple mechanicalconstruction might be employed.

Having now brieii y described the parts involved in my invention, Ishall describe their operation. The hose-couplings are screwed 5 5 ontothe hydrant-plugs in the ordinary Way before the Water is turned at themain by the central valve-rod. In so screwing them on the extension-ringI in the coupling J presses against the cylindrical sleeve D in the plug6o A, thus pushing the valve B from its seat sufficiently far to admitof the free escape of water. ,The Water is now turned on at the main andmakes its Way through the plug into the hose. Should, however, one ofthe hose burst, as is often the case at a fire, instead of turning offthe Water at the main, and thus preventing the use of the other length,it is merely necessary to unscrew the one length, when the pressure ofthe water will immedi- 7o ately close the valve and prevent the escapeof water. Another length of hose may now be immediately substituted, andas it is being screwed on will reopen the valve and again permit thefree escape of water through the hose. It will be seen that eithercoupling may be taken off at the will of the iiremen or person using thehose and taken to another hydrant Without interfering with the flow ofthe Water. It will also be understood that 8o the water may be turned onfull, and the valves being self-closing prevent the escape of the wateruntil the coupling or couplings of the hose are attached.

In order to prevent the possibility of the valve and sleeve falling intothe hydrant, I make a slot K in the the sleeve D, and insert a Screw kthrough the plug A, to form a stop, as shown. The slot K is madesufficiently long to allow the free movement of the valve. 9o

In a pending application, filed February 10, 1890, Serial No. 339,852, Ihave shown a valve for hydrants automatically operated by the pressureof the water, the said valve' being connected by a sliding sleeve, thesleeve bein gprovided with apin which proj ects through :t slot in theplug in position to be moved by the couplingwhen the saine is securedthereon, and I do not claim this construction.

That I claim as my invention is- 5 In a hydrant, zt valve, a slidingsleeve litting the Walls ofthe plug, Said valve being con neoted to saidsleeve by extensions in direct line therewith, und a. Couplingengagingwith the plug and having an eXtension-iingI, said extensionbeingr circular in eross-section and m also fitting the Walls of theplugand abutting against the end of the sliding sleeve, the i11- teiiorof the plug being left free for the uninterrupted oW of the Water.
